In this area the geology consists of Karmutsen Formation andesites and minor limestone in contact to the southwest with Quatsino Formation limestone both of the Upper Triassic Vancouver Group.

Chalcopyrite and minor bornite occur in a narrow, strongly altered zone in andesite striking northwest and dipping 50 degrees east. Calcite, epidote and quartz are found in fractures and amygdules. Copper mineralization is scattered across an approximately 10 metre width to the east.
